TSA™ Signal Amplification for IHC, ICC, IF

The extraordinary sensitivity of the Tyramide Signal Amplification (TSA™) kits from PerkinElmer lets you see previously undetectable levels of protein and nucleic acid. The resolution is remarkable. And with multi-target detection, you can get more information from each experiment. It’s clear to see. TSA makes it easy to gain valuable insight from your immunohistochemistry (IHC) and immunocytochemistry (ICC) results.

TSA™ Signal Amplification for ISH

Tyramide Signal Amplification (TSA™) provides remarkable sensitivity enhancement for your ISH experiments without the drawbacks associated with other methods. Signal amplification with TSA allows detection at levels as low as asingle copy and enables the use of shorter probes for more precise localization of targets. The TSA reaction occurs within 10 minutes, and labels are bonded covalently, ensuring outstanding resolution.
